When does a defense attorney's trial strategy constitute ineffective assistance of counsel? State v. Roberts Explained

In State v. Roberts, the Utah Court of Appeals addressed multiple claims of ineffective assistance of counsel arising from defense counsel’s strategic choices during a sexual abuse trial. The case provides important guidance on the high bar defendants must meet when challenging their attorney’s trial strategy.

Background and Facts

Roberts was convicted of aggravated sexual abuse of a child after his adoptive sister testified that he inappropriately touched her when she was seven years old. During trial, the prosecutor made statements during closing argument about Roberts’s position relative to the victim that defense counsel objected to, and cross-examined Roberts’s mother about a DCFS investigation. Defense counsel chose not to attack the victim’s credibility, instead focusing on Roberts’s lack of sexual intent.

Key Legal Issues

Roberts raised several issues on appeal: whether the prosecutor’s closing argument statements warranted a mistrial or limiting instruction; whether the prosecutor’s cross-examination of his mother constituted misconduct; and whether defense counsel was ineffective for not requesting a bill of particulars, not challenging the victim’s credibility, and not requesting various remedies for alleged prosecutorial misconduct.

Court’s Analysis and Holding

The court applied the Strickland standard for ineffective assistance claims, requiring both deficient performance and prejudice. The court emphasized that “judicial scrutiny of counsel’s performance [is] highly deferential” and that courts need only “articulate some plausible strategic explanation for counsel’s behavior.” Only when “no reasonable attorney” would pursue the chosen strategy will a court find constitutional ineffectiveness.

Regarding defense counsel’s decision not to attack the victim’s credibility, the court found this was reasonable given the victim’s emotional testimony and Roberts’s own admissions. Defense counsel could rationally focus on intent rather than appear unsympathetic by attacking a vulnerable witness.

Practice Implications

This decision reinforces the strong deference given to defense counsel’s strategic choices. When challenging trial strategy on appeal, practitioners must demonstrate that no reasonable attorney would have pursued the chosen approach, rather than simply arguing that alternative strategies might have been superior. The case also illustrates that Rule 23B remands are not available when the existing record demonstrates counsel’s performance was reasonable, even if additional facts might provide more context for the strategic decisions.
